IMPROVEMENTT IN TRAVERSING MACHINE.

Specification forming part of Letters Patent No. [05,930, dated August2, 1870.

I, VALENTINE FOLAND, of Indianapolis, in the county of Marion and Stateof Indiana, have invented certain Improvements in Traversing Machines,of which the following is a specification Nature and Objects of theIntention.

The invention consists, first, in mechanism to convert rotary intoreciprocating motion,

and applying it to propel traversing and other tools, the parts having'such relations to each other that mortising and boring attachments maybe applied to the machine, and operated simultaneously or separately. Italso consists of a feeding device, whereby the stuff can be fed up ineither direction orthrown out of gear at pleasure. r

Description of Accompanying Drawing.

Figure 1 is an end elevation of a machine embodying my invention. Fig. 2is a top view.

Fig. 3 is an inverted view of the table D. Figs.

4, 5, 6, and 7 relate to parts which will be described in the course ofthis specification.

.The sameletters of reference indicate like parts in the severalfigures.

' General Description.

- A is the frame of the machine. Bis the driving-pulley, which is hungon the main shaft. 0 of the machine, from which latter mo- M, Fig. 1, isa rod fastened to the plate 0, having screw-threads traced on it. n is anut, whichcan be adjusted to difl'erent points on the rod M. n is apiece fastened to the crosshead, and limits its descent by" coming incontact with nut n. The slider E is reciprocated by means of the crank Nand connectingrod N.

In Fig. 5, a is a block, with the mortise a running through with theproper angle to receive the traversing bit a. c is a tightening bolt orscrew, to fasten and hold the bit. K

is a double-slotted tool-carrier, to receive the block a. It has theslot 1), (see Fig. 6,) to embrace the flange E. The tightening-bolts bhold it to its place. The slot b receives the tool-stock a, which ispivoted therein by the pin e. A spring, '6, holds the bit down to itswork, and allows it to yield therefrom on the reverse motion. Thesebit-stocks are made right and left, one of each being used fortraversmg.

L, Fig. 7, is a tenonin'g-tool. It has the slot or groove 6, hywhichitis attached to the slider. It is fastened by screws 6. It carries thebit m and the shoulder-cutter m.

P, Fig. 1, is a cross-cutting saw. It is held in a frame consisting ofthe slider E and the pieces .9 s, and the saw is stretched by screws 8at the top, obtaining a leverage on the pieces 8. The pieces 8 and thesaw are removed when the machine is used as a traverser. D is a slidingcarriage or table, in

which the stuff to be operated on is placed.

Y, Fig. 3,'are cog-segments. w is a pinion on an upright shaft, whichhas hearings in the sliding block Q, Fig. 1. This shaft and pinion arerevolved by the bevel cog-wheels R R.

The worm-wheel T gives motion to the shaft U and wheel B. through thepinion t.

V is a lever, working on a pin, 22, as a fulcrum. It is attached at oneend to the block Q; the other end serves as a handle to shift block Q.There is a catch on the lower side of lever V, which fits into notches non the piece W. This arrangement is for holding the block Q in any oneof its positions for propelling table D in either direction, or for letvting the pinion w remain out of gear.

The travel of the carriage D is reversed by shifting the lever V byhand, or it may be thrown out of gear.

X is a supplemental table, secured on table D by the comb-clamps D.Various operations may be performed on this second table, as sawing,tenoning, 850. d is a lever, for holding the stuii'. g is a'movableclamp, to gage it.

The operation of the machine will beobvious from the drawing and theabove descrip tion'.

' Claims.

1 claim as my invention 1. The reciprocating sliding bar E, whenconstructed, arranged, and operated substangearing R, R, t, and T, andthe pinion w, and tia lly as and for the purpose hereinbefore setsegment Y, substantially as and for the purforth. pose hereinbefore setforth.

2. The tool-carrier K and bit-block a, corn VALENTINE FOLAND. struetedand combined substantially as and Witnesses: V for the purposehereinhefore set forth. SPENCER HIATT,

3. The shifting block Q, combined with the JOHN POLLITT.
